Application January 4,

4 Claims.

are not true due to many causes, such as insufiicient seasoning, careless handling, improper casting, or warping.

It is primarily an object of the invention to which will with proper use right angle or such angle can be adjusted either way up to .005 of an inch.

A more particular object of the invention is to provide an angle plate wherein the flanges of the plate have associated therewith means for adjusting said flanges one partly in end elevation and an angle plate constructed an embodiment of my integral. The angle plate at the junction of the flanges l and 2 is provided with a groove 3 extending from one end to the other whereby the and 2 may have relative flexure along such junction portion.

The rear face of one of the flanges, as I, adjacent to its opposite ends is provided with the rearwardly and downwardly disposed rigid arms 4. and the lower or free portion of each of the 1938, Serial fixedly mounted thereon, an upstanding block 8 and said flange 2 fore and aft of the block 8 is also provided with the reinforcing or strengthening ribs 9. Extending outwardly from each of the blocks 8 is a threaded post 10 of desired length and which freely extends through the free end portion of the adjacent arm 4 and up into the pocket 5 thereof. Threaded upon this post H] are the nuts II and [2. The nut ll coacts with the end face 1 of the arm 4 while the nut l2 coacts' with the base 6 of the pocket 5. Interposed between the nut H and the end face 1 is a washer l4 and a second washer I5 is interposed between the base 6 of the pocket 5 and the nut l2. The post l0 may be held to its block 8 in any desired manner but, as herein disclosed, an end portion of said post Ill threads into the block. I

If the flanges l and 2 of the angle plate should be out .010 it can be pulled into accuracy by proper manipulation of the nut l 2 which will pull inwardly, and when the been effected the second or under nut II will serve as a lock nut to maintain such adjustment, It is to be understood, of course, that previous to adjusting the nut l2 to pull the flange or side I inwardly, the other nut II will have been turned away from the end face 1.

Should the flanges or sides I and 2 of the angle plate be less than ninety degrees, the nut H is used to push upon the arm 4 until the desired accuracy is obtained whereupon the nut I2 is adjusted to provide the required lock.

From the foregoing be obvious that an I claim:-

1. As a new article of manufacture, an angle plate comprising two angularly related integrally connected and flexible flanges one with respect to the other, and coacting means carried by both of the flanges for spreading or retracting one of the flanges with respect to the other.

2. As a new article of manufacture, an angle plate comprising two angularly related connected flanges, and coacting means carried by both of the flanges for spreading or retracting one of the flanges with respect to the other, said angle plate being provided in the joining portions of the flanges with a groove to facilitate the flexing of one flange with respect to the other.

3. As a new article of manufacture, an angle plate comprising two angularly related connected flanges, an arm carried by one of the flanges and disposed at the same side thereof as the second flange, an elongated member carried by the second flange and extending through the free end portion of the arm, a nut threaded upon the elongated member to engage the arm to spread the flanges, and a second nut threaded upon the elongated member outwardly of the arm to retract the flanges.

4. As a new article of manufacture, an angle plate comprising two angularly related connected flanges, an arm carried by one of the flanges and disposed at the same side thereof as the second flange, an elongated member carried by the second flange and extending through the free end portion of the arm, a nut threaded upon the elongated member to engage the arm to spread the flanges, and a second nut threaded upon the elongated member outwardly of the arm to retract the flanges, one of said nuts serving as a lock to hold the flanges in the adjustment made by the second nut.
